Supplies:

First, I divided the poster board into equal sized rectangular strips. I marked each strip with a diagonal line.

Next I cut each strip and then hand drew the shape I wanted at the tip of each sunburst petal. After drawing each petal, I cut out the shape of each petal point.

Once all of the tips were cut, I cut a circle from a piece of cardboard. I spray painted the cardboard black to match the black mirror I used for the center. Once the cardboard dried I hot glued the mirror to the center of the cardboard.

In order to create the shorter petals in the center of the sunburst, I cut off most of the length of the strip. I did the same for the second layer of petals only I cut off a little less of the length of the strip.

I began hot gluing the petals starting with one of the shortest positioned at the north, south, east and west positions of my cardboard circle.

I continued filling in petals and layering until I had the finished project below. The full size of the sunburst is 36 inches by 36 inches.
